10kv 250kVA Hermetically Sealed Oil-Immersed Three 3phase Power Distribution Transformer
Oil-immersed Transformers Product Details:
Oil-immersed transformers represent a pivotal advancement in power equipment, indispensable for power systems, particularly in voltage conversion and power transmission roles. Crafted to cater to high current demands and substantial capacity requirements, these transformers exhibit unparalleled stability and reliability, making them essential for efficient power systems.
 

Model Meaning:
10kv 250kVA Hermetically Sealed Oil-Immersed Three 3phase Power Distribution Transformer
 

Performance Characteristics:

1. Winding structure:
Our high-voltage winding employs a sophisticated multi-layer cylindrical, continuous or connecting continuous structure, significantly enhancing shock distribution. This design ensures minimal magnetic leakage, robust mechanical strength, and exceptional short-circuit resistance, setting the bar for industry standards.

2. Iron core design:
Utilizing top-tier cold rolled grain-oriented silicon steel sheets with a full diagonal seam stacking method, our design significantly curtails no-load loss and no-load current, optimizing efficiency.

3. Fastening and anti-loosening:
Each core and winding is secured with strategic fastening solutions. High and low voltage leads are equipped with self-locking anti-loosening nuts and a non-hanging center structure, ensuring resilience during transportation. All fasteners are equipped with fastening nuts to maintain integrity during prolonged operation.

4. Vacuum processing:
Our coils and cores undergo meticulous vacuum drying, while transformer oil receives vacuum filtering and injection to eliminate moisture, preserving the integrity and longevity of the transformer.

5. Oil tank design:
The innovative oil tank features corrugated sheets with breathing capabilities, adapting to temperature-induced volume changes without needing an oil storage cabinet, effectively reducing the transformer's height.

6. Other features:
With a sleek design, compact size, and minimal installation footprint, this product is the quintessential maintenance-free solution, ideal for contemporary needs.
Our oil-immersed transformers are extensively adopted across power plants, substations, industrial and mining enterprises, and rural power grids, serving as pivotal components in modern power distribution systems.
 
Environment and Requirements:
Ambient temperature: Recommended range from -25°C to +40°C for optimal performance.
Altitude limit: Should not exceed 1000m to ensure reliable operation.
Air humidity: Keep relative humidity levels at or below 90% (at +25ºC) to maintain optimal efficiency.
Installation place: Select an area devoid of corrosive gases and significant dirt to ensure longevity and reliability.
 

Maintenance and upkeep:
Regular inspection: Conduct frequent checks on oil levels and test oil insulation strength. Promptly replace transformer oil if any issues are detected.
Stable operation: Ensure consistent and stable transformer operation by avoiding overloads, short circuits, and other anomalies.
Safety attention: Prioritize ventilation and fire prevention during installation, adhering strictly to technical specifications for safe and correct setup.
